I don't care who has direct involvement or knowledge; you're accountable for what you operate and if you operate something with rampant scams then you're accountable for that.

They're operating a platform that enables criminal activity and they benefit from it. They've been told this (and even without it, they can and should have known). And then they elected to not do all that much about it. "Don't do anything" is just as much of a decision as "do something" is.

Last time I looked at this they were literally recommending scams with "Amazon's Choice"[1]. That one is now gone, but you just need to "sort by price" (a reasonable thing to do) to find tons of scams.[2] None of this is new information. This has been going on >10 years. There's tons of stories about this sort of thing.

"Yeah, there's tons of scams on our site, and yeah, we're making a profit off those scams, but what can we do?" just doesn't fly. Rampant illegal activity you're making a profit on but somehow no one is accountable? Screw that.
